From reading and searching this site I have seen many mentions of the 40 oil pressure gauge having a tendency to break and/or give inaccurate readings. My new 76 40 is registering very low according to the gauge i.e. never gets above L in any condition. The truck runs like a top.
Where can you manually check the pressure and what do I need to do about the gauge i.e. replace sending unit/gauge/both?
Thanks.
